     13 1. OVERVIEW
     14 
     15 The file iwlwifi-6000-4.ucode provided in this package must be 
     16 present on your system in order for the Intel Wireless WiFi Link
     17 AGN driver for Linux (iwlagn) to operate on your system.
     18 
     19 The "-4" in the filename reflects an interface/architecture version number.
     20 It will change only when changes in new uCode releases make the new uCode
     21 incompatible with earlier drivers.
     22 
     23 On adapter initialization, and at varying times during the uptime of 
     24 the adapter, the microcode is loaded into the memory on the network 
     25 adapter.  The microcode provides the low level MAC features including 
     26 radio control and high precision timing events (backoff, transmit, 
     27 etc.) while also providing varying levels of packet filtering which can 
     28 be used to keep the host from having to handle packets that are not of 
     29 interest given the current operating mode of the device.
     30 
     31 2. INSTALLATION
     32 
     33 The iwlagn driver will look for the file iwlwifi-6000-4.ucode using the 
     34 kernel's firmware_class infrastructure. More information can be found under
     35 Documentation/firmware_class in kernel source. In order to function
     36 correctly, you need to have this support enabled in your kernel.  When 
     37 you configure the kernel, you can find this option in the following 
     38 location:
     39 
     40         Device Drivers ->
     41                 Generic Driver Options ->
     42                         Userspace firmware loading support
     43 
     44 
     45 You can determine if your kernel currently has firmware loader support 
     46 by looking for the CONFIG_FW_LOADER definition on your kernel's 
     47 .config.
     48 
     49 In addition to having the firmware_class support in your kernel, you
     50 must also have a working udev and uevent infrastructure configured.
     51 The steps for installing and configuring udev are very
     52 distribution specific. 
     53 
     54 Once you have the firmware loader in place (or if you aren't sure and 
     55 you just want to try things to see if it works), you need to install 
     56 the microcode file into the appropriate location.
     57 
     58 Where that appropriate location is depends (again) on your system 
     59 distribution.  You can typically find this location by looking in the 
     60 udev scripts of your distro, the default is /lib/firmware.
     61 
     62 Installation of the firmware is simply:
     63 
     64         % cp iwlwifi-6000-4.ucode /lib/firmware
     65 
     66 You can now load the driver (see the INSTALL and README.iwlwifi provided with
     67 the iwlwifi package for information on building and using that driver.)
